Regenerative Blowers Comprise Cast Aluminum Housing

Ametek’s two new Rotron brand regenerative blowers satisfy a wide range of industrial applications. They can agitate solutions, convey parts and products, perform vacuum hold-down and pick-up operations, dry and clean parts, or sample process and off gase.

These blowers (Models DR333 and DR433) incorporate compact, rugged construction engineered for reliable and long service life at point-of-operation. They employ regenerative air technology to develop proper air pressures and vacuums without the higher energy and maintenance costs associated with larger multi-stage or positive air-displacement blowers and compressors.

Rotron DR333 blowers can achieve maximum flows up to 58 SCFM, pressures up to 10.8 PSIG (300 IWG), and vacuums up to 17.5 IHG (240 IWG).  The DR433 versions can develop maximum flows up to 110 SCFM, pressures up to 13 PSIG (360 IWG) and vacuums up to 17.6 IHG (183 IWG).

Both models feature rugged cast aluminum housing, impeller, and cover; threaded cast iron flanges; and UL approved 3-phase TEFC motors with permanently sealed ball bearings contributing up to 25,000 hours of service life.  The motors can be specified to handle a broad range of international voltage and frequency options.
